Detailed Description

Defines a polar grid surface mesh.

Class to define a surface mesh represented by a grid with polar coordinates. This mesh is defined by a matrix num_r * num_t points forming (num_r - 1) * (num_t - 1) quadrangles. Each point with index (i, j) in the mesh (except for points along the mesh border) is connected to four points with indices (i+1,j), (i,j+1), (i-1,j), (i,j-1). r is an array of num_r radius, t an array of num_t angles, and z an array of num_r * num_t floats.

The values on the mesh nodes are defined by the PbMesh::addValuesSet(set_index,val) method, where val argument is an array of num_r * num_t floats.
